Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"mobile learning predation algorithm" » "mobile learning predators algorithm", "mobile learning estimation algorithm", "mobile learning prediction algorithm", "mobile learning emotion algorithm", "machine learning predation algorithm"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified notion optimization algorithms") OR ("mobile learning predation algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) or ( mobile learning predation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") or ("mobile learning predation algorithm"))*.
